Abstract (en)
[origin: DE19614565A1] The use of bio-degradable organic polymers with a mean molar mass of over 500 in hydraulic cooling systems, in which the aqueous phase of the cooling system additionally contains 0.05 to 5 mg/l of an oxidant with a more positive standard redox potential than oxygen.
